Abstract

The present invention provides a method of position sensing between a wireless mobile component carrying a mobile ultrasonic transducer and a fixed component carrying a plurality of fixed ultrasonic transducers in a predetermined spaced-apart relationship, the method comprising sending an rf trigger signal from the second rf transducer, sending an rf acknowledgement signal from the first rf transducer responsive to receipt of the rf trigger signal, receiving the rf acknowledgement signal at the fixed component and starting a plurality of timers corresponding to the respective plurality of fixed transducers generally simultaneously with receiving the acknowledgement signal, transmitting a signal from the mobile ultrasonic transducer responsive to the received trigger signal, receiving the signal transmitted by the mobile ultrasonic transducer at each fixed ultrasonic transducer and stopping the respective timer generally at the time of reception of an edge of the received signal, calculating the distance between the mobile ultrasonic transducer and each fixed ultrasonic transducer based on a predetermined constant representative of the speed of sound and the time taken for transit of the signal to each fixed transducer as measured by the respective timers, and performing trigonometric calculations using the calculated distances in order to determine the 3-dimensional position of the mobile component relative to the fixed component.
